In this bold and radical book, award-winning science journalist Angela Saini goes in search of the true roots of gendered oppression, uncovering a complex history of how male domination became embedded in societies and spread across the globe from prehistory into the present. Travelling to the world's earliest known human settlements, analysing the latest research findings in science and archaeology, and tracing cultural and political histories from the Americas to Asia, she overturns simplistic universal theories to show that what patriarchy is and how far it goes back really depends on where you are. Saini ends by asking what part we all play - women included - in keeping patriarchal structures alive, and why we need to look beyond the old narratives to understand why it persists in the present.
